Background Multiple cases of dissociation of the head from the neck termed as gross
trunnion failure (GTF) in total hip replacement have been described. Very little quantitative …

Corrosion of taper connections in total hip arthroplasty remains of concern, as particles and
ions generated by corrosive processes can cause clinical problems such as periprosthetic …

Abstract Modern Total Hip Arthroplasty (THA) has evolved allowing orthopaedic surgeons
for an exact reconstruction of hip biomechanical parameters thanks to modularity. Modular …

Background: The Accolade TMZF is a tapered-wedge cementless metaphyseal-coated
femoral stem that was widely utilized from 2002 to 2012. In recent years, there have been …

Background: Corrosion at the head-neck junction of femoral stems is a rare complication of
total hip arthroplasty (THA) with manifestations ranging from subclinical wear to failure. Prior …

This work aimed to investigate the effect of the burnishing surface treatment on the
tribocorrosion resistance related to Ti6Al4V specimens, in the framework of the head-neck …

Background Gross taper failure (GTF) is a rare but catastrophic failure mode of the head-
stem-taper junction of hip prostheses, facilitated by massive material loss. GTF is a two stage …

Introduction Corrosion at the head–neck interface of modular components in total hip
arthroplasty (THA) has been reported as a cause of failure of modern total hip replacement …

Conclusion: This case demonstrates that GTF at the head-stem taper junction following
mechanically assisted crevice corrosion is not limited to a specific taper design and material …

Total Hip Arthroplasty (THA) has been a foundational tenant in orthopedic reconstructive
surgery for decades. Design improvements have contributed to improved outcomes …
